5.4 Creating Routes
In many cases a trip from one place to another involves several course changes, requiring a
series of route points (waypoints) which you navigate to, one after another.
The sequence of waypoints leading to the ultimate destination is called a route. The
RP-180 can automatically advance to the next waypoint on a route, so you do not have to
change the destination waypoint repeatedly. The figure below shows an example of a route
between two ports, involving six waypoints.
You can store up to 10 routes. A route may contain up to 30 waypoints.
